Coding circuit 129 is connected to above-mentioned rectification circuit 123, it is the circuit that detects the receiving sensitivity of the electric wave that receives by antenna 12, in the present embodiment be for example quantize above-mentioned receiving sensitivity information, concrete be to receive voltage, in other words be the circuit of the output voltage of rectification circuit 123.Receiving sensitivity information 1291 after coding circuit 129 will quantize is in the present embodiment delivered to control part 126.This coding circuit 129 for example can wait the morphosis of count frequency to utilize A/D change-over circuit and voltage counting circuit (VCO).Certainly the output form of coding circuit 129 is not limited to the above-mentioned form that quantizes, and can adopt various output forms according to the detection of above-mentioned receiving sensitivity.For example, also can adopt the form of Word message and graphical information etc.
Above-mentioned control part 126 is carried out from the order of the regulation of receiving circuit 125 supplies, under the situation that data write, its result is written in the information storage part 127, when data are read, the data of sense information storage part 127, and return from loop aerial 12 through transtation mission circuit 128.For example, if send to make and be recorded in the instruction that the fuel data in the information storage part 127 is returned, data in the control part 126 sense information storage parts 127 then, methanol concentration numeric data for example, and in transtation mission circuit 128 as the radio wave that is modulated to radio band and power supply to loop aerial 12 and return.In addition, except above-mentioned concentration data, also stored and content and at least one relevant management information 1271 of holding the storage container of this content in the information storage part 127.As the management information 1271 relevant for example kinds of information of expression foregoing thing is arranged, or arranged the period of for example making of the above-mentioned storage container of expression and use the information of historical at least one as the management information 1271 relevant with above-mentioned storage container with the foregoing thing.When reading, read at least one in these information.
In the RFID label 101 of present embodiment, control part 126 is the receiving sensitivity information 1291 to supplying with from coding circuit 129 further, be modulated to radio band by transtation mission circuit 128, and as radio wave, carry out power supply to loop aerial 12 and the control returned.
If describe in detail, then the received power of antenna 12 and transmitted power, send sensitivity, receiving sensitivity is relevant, but shown in the relation of the power output of the above-mentioned rectification circuit 123 that changes according to receiving sensitivity of Fig. 4 and communication distance, be subjected to most about the distance between said external transceiver and the RFID label 101.As already explained, only both can communicate under the characteristic by voltage standard circuit 124 makes between said external transceiver and the RFID label 101 than the short situation of predetermined distance, promptly as shown in Figure 5, only when antenna reception voltage has surpassed the thresholding incoming level of regulation, produce certain action power voltage from voltage standard circuit 124.We can say conversely, can estimate distance between RFID label 101 and the said external transceiver by the reception magnitude of voltage in the RFID label 101.That is, the liquid level meter that can be used as the liquid in the storage container uses.Therefore, in the present embodiment, constitute, and this numerical value is turned back to the said external transceiver by quantize received power in the RFID label 101 of coding circuit 129.
In addition, in the RFID of present embodiment label 101, adopted the receiving sensitivity information 1291 after quantizing as mentioned above to turn back to the form of said external transceiver, but also can followingly constitute.That is, control part 126 has transformation component 1261 as shown in Figure 2.Transformation component 1261 replaces above-mentioned receiving sensitivity information 1291, will be corresponding to the information of above-mentioned receiving sensitivity information 1291, promptly as information outside the above-mentioned receiving sensitivity information and conversion the information converting of above-mentioned receiving sensitivity information deliver to the said external transceiver from transtation mission circuit 128.Above-mentioned information converting for example is the range information between said external transceiver and the RFID label 101, transformation component 1261 for example also can utilize set arithmetic expression to calculate above-mentioned information converting from above-mentioned receiving sensitivity information 1291, or, the storage part 1262 that also can be in advance the form stores that above-mentioned receiving sensitivity information 1291 and above-mentioned information converting is associated describe be had in transformation component 1261 sends the above-mentioned information converting of reading from storage part 1262 from transtation mission circuit 128.
As an application examples of RFID label 101 with as above illustrated structure, shown in Fig. 6 A and Fig. 6 B, adopt sending/receiving system 190 for example with said external transceiver 180 and RFID label 101, the following describes this system 190.In addition, the surplus to liking liquid by these sending/receiving system 190 management is a liquid level.
Outside transceiver 180 is to dispose non-contactly with RFID label 101, and the device that carries out information exchange with RFID label wireless the communicating of 101 usefulness has the acceptance division 160 of transmission and dispensing device side control part 170.Send acceptance division 160 and be that the antenna 12 that has with RFID label 101 communicates as the coil antenna 161 of the input/output terminal of electromagnetic induction and the transmitter/receiver circuit 162 that electromagnetic induction is used, send electric waves to RFID label 101, receive the receiving sensitivity information 1291 sent from RFID label 101 or should outside transceiver 180 and the part of the range information 140 of RFID label 101 simultaneously.Dispensing device side control part 170 is the parts of carrying out the action control of this outside transceiver 180.
In addition, because outside transceiver 180 is configured in equipment side, so can be bigger circuit scale.
As mentioned above, RFID label 101 returns the reception magnitude of voltage as receiving sensitivity information 1291 in the present embodiment.Thus, have in the dispensing device side control part 170 of outside transceiver 180 according to above-mentioned receiving sensitivity information 1291 obtain range information 140 between this outside transceiver 180 and the RFID label 101 apart from determination section 171.For example also can utilize set arithmetic expression from above-mentioned receiving sensitivity information 1291, to calculate range information apart from determination section 171, or in this dispensing device side storage part 1711 that is had apart from determination section 171, store the form that makes above-mentioned receiving sensitivity information 1291 and range information 140 be associated and describe in advance, and from dispensing device side storage device 1711, read range information 140 by the portion of reading 1712.
Resulting range information 140 is sent from dispensing device side control part 170.
In addition, under the situation that adopts the form of sending range information 140 from RFID label 101, dispensing device side control part 170 is sent by sending the range information 140 that acceptance division 160 receives and supplies with.
This dispensing device side control part 170 also can be connected on the display unit 185 of for example visual display liquid level level, and constitute a liquid level meter by this sending/receiving system 190, as appending explanation, also can constitute the control device of further range information 140 being delivered to the higher level.
Sending and receiving methods in as above illustrated such sending/receiving system that constitutes 190 is described.
If the basic transmission of explanation receives action, then send acceptance division 160 and be controlled to be by predetermined output voltage and send.Received the RFID label 101 of electric wave of certain output of this regulation, RFID label 101 be positioned at can communicate by letter apart from the time, as mentioned above, generate builtin voltage by receiving electric wave, carry out the coding of receiving sensitivity simultaneously, in the present embodiment, carry out the quantizing of output voltage of rectification circuit 123.In addition, also there is the situation that writes and read carry out with the data of information storage part 127.And, turn back to dispensing device side control part 170 from RFID label 101 with the reception information of voltage 1291 after quantizing or according to the range information 140 after these reception information of voltage 1291 conversions.
As shown in Figure 6A, under the situation about being full of by liquid 151 in storage container 150, RFID label 101 swims on the position of liquid level 151a, with the distance 140 of the antenna 161 of outside transceiver 180 be apart from 140-1.If this communication distance 140-1, then outside transceiver 180 and communicating by letter of RFID label 101 can be abundant, and the power that RFID label 101 is received is also big, and the direct voltage of the output of rectification circuit 123 is also high.
Then, shown in Fig. 6 B, the liquid 151 in having consumed storage container 150, with the distance 140 of the antenna 161 of outside transceiver 180 be that it is far away that communication distance becomes under the situation apart from 140-2.At this moment, the voltage step-down of electromagnetic induction in the antenna 12 of RFID label 101 then, becomes below the threshold level of input voltage of voltage standard circuit 124.Thus, RFID label 101 becomes the state that is not supplied to power supply.Because in the RFID label 1291, supply line voltage does not receive information of voltage 1291 or range information 140 so RFID label 101 can not return.Thus, because not from the returning of RFID label 101, so outside transceiver 180 is judged as liquid 151 for below the ormal weight, or storage container 150 does not exist itself.
In addition, the boundary line of communication distance can be stipulated by by voltage standard circuit 124 supply voltage being set.
In above-mentioned example, by not returning from the information of RFID label 101, the surplus that detects liquid 151 is below the ormal weight, even but also can be formed in when not having liquid 151 in the storage container 150, also from RFID label 101, return and receive information of voltage 1291 or range information 140.Represent one embodiment below.
Outside transceiver 180 for example sends the command signal to RFID label 101 of modulating with the frequency of 13.56MHz with the output of 30mW as an example.When externally the distance 140 of the loop aerial 12 of the loop aerial 161 of transceiver 180 and RFID label 101 was 15mm, the direct voltage that takes out from the carrier wave composition of 13.56MHz by rectification circuit 123 was 6.2V.In addition, when externally the distance 140 of the loop aerial 12 of the loop aerial 161 of transceiver 180 and RFID label 101 was 30mm, the direct voltage that takes out from the carrier wave composition of 13.56MHz by rectification circuit 123 was 1.5V.In addition, each value of being put down in writing here is the value among the embodiment.
Like this, if distance 140 differences between the loop aerial, then from rectification circuit 123, send different dc voltage values, the above-mentioned dc voltage value that control part 126 storages of RFID label 101 are supplied with from coding circuit 129, from outside transceiver 180 return when inviting, return this magnitude of voltage.
The received power of RFID label 101 is directly proportional with the transmitted power of outside transceiver 180, roughly with square being inversely proportional to of communication distance 140, so can easily estimate the distance 140 of the antenna 12 of the antenna 161 of outside transceiver 180 and RFID label 101, thus, can also estimate liquid level.In practicality, for the source of error of the reflection that reduces the reception electric wave around the RFID label 101 etc., preferably use the inner capacities of having described the liquid 151 in the storage container 150 in advance and the evaluation form of the relation of the above-mentioned dc voltage value supplied with from coding circuit 129.
In above-mentioned sending/receiving system 190, the liquid 151 that holds in this storage container 150 changes, and under the outer container 152 indeformable situations of storage container 150, the structure of RFID label 101 for swimming on the liquid level 151a of liquid 151 still also can adopt the structure shown in Fig. 7 A and Fig. 7 B.
In the sending/receiving system shown in Fig. 7 A and Fig. 7 B, the outer container 1531 of storage container 153 is by according to the telescopic parts of inner capacities varied appearance shape as the liquid 151 of an example of content, and for example the elastomeric element of elastomeric material etc. constitutes.Thus, the inner capacities variation with liquid 151 is complementary the height change of outer container 1531.Therefore, by on respect to the opposed faces 1532 of the outer container 1531 of outside transceiver 180, RFID label 101 being installed, thereby the variation of the distance 140 between outside transceiver 180 and the RFID label 101 increase and decrease as inner capacities can be detected.Fig. 7 A is illustrated in the state of full of liquid 151 in the outer container 1531, and Fig. 7 B represents the state that the liquid 151 in the outer container 1531 reduces.
In addition, outer container 1531 also can form its integral body by same parts, material, but also can make parts, material part difference.For example, no matter above-mentioned opposed faces 1532 is the variation of the height of outer container 1531, and that outside relatively transceiver 180 is kept the state of almost parallel is best on measuring.Thus, opposed faces 1532 is used the big material of the hardness of very difficult distortion etc., can adjust the distortion situation of storage container 153 according to the position.Like this, even under the situation of the posture change of storage container 153, because range information 140 still keeps invariable, so the variation that can high-acruracy survey goes out inner capacities.
In addition, also can adopt as shown in Figure 8 structure.In the sending/receiving system shown in Figure 8, the outer container 1541 of storage container 154 is indeformable, but the edge is equivalent on the illustrated Z-direction 145 of vertical direction movable next door parts 1542 are set in outer container 154., extrude outside outer container 1541 according to along the moving of the next door parts 1542 of the inwall of outer container 1541 as the liquid 151 of an example of inner thing.Therefore, next door parts 1542 move according to the inner capacities variation of liquid 151.Therefore, by relative next door parts 1542 configuring external transceivers 180, and RFID label 101 is installed on the next door parts 1542, can detects the variation of the distance 140 between outside transceiver 180 and the RFID label 101, with increase and decrease as inner capacities.In addition, in storage container 154, by guaranteeing the air-tightness between next door parts 1542 and the outer container 1541, even the posture change of storage container 154 can prevent that also liquid 151 from spilling to the outside, or extraneous gas enters in the outer container 1541.At this moment, because next door parts 1542 only move along Z-direction 145, so even under the situation of the posture change of storage container 154, range information 140 also can be measured the variation of inner capacities accurately for constant.
In addition, the structure of sending/receiving system is not limited to above-mentioned this, in addition, can constitute sending/receiving system in the scope that those skilled in the art expect easily.
Then, Fig. 9 represents to have the example of application system of sending/receiving system 190 grades of above explanation.In the application system 201 shown in Figure 9, as a power supply in the electronic equipment 210, use direct methanol fuel cell 220, use above-mentioned sending/receiving system 190 in the surplus management of the methanol solution 1511 in the fuel storage container 150 that this cell of fuel cell 220 is had.At this,, be equivalent to for example such portable electronic device of notebook personal computer as above-mentioned electronic equipment 210.In addition, the storage container 150 that has held methanol solution 1511 adopts with respect to cell of fuel cell 220 structure removably.In addition, methanol solution 1511 is not only methyl alcohol stoste, also comprises the notion of the methanol aqueous solution that is adjusted into the concentration that is suitable for generating electricity.Further, acting as a fuel and lifting methyl alcohol is example, but is not limited to methyl alcohol.In addition, also can use the liquid of solution of for example boron hydride being dissolved in the alkaline aqueous solution etc. to be used as fuel.
As mentioned above, because IC chip 120 can produce microsize, so RFID label 101 itself also can be made with the size about several millimeters angles.Therefore, by using RFID label 101, at first, though says can be relatively as on the electronic equipment 210 of portable usefulness the small-sized fuel storage container 150 of loading load and unload, and can detect inner capacities and divide only.In addition, because RFID label 101 light weight, so for example the form shown in Fig. 7 A and Fig. 7 B is such, on outer container 1531 on 1532 under the situation of attaching rfid tag 101, can reduce measure error, and can not make outer container 1531 distortion, or do not limit the effect of adhesion locations in addition because of the deadweight of RFID label 101.
Further, as the method for organize content amount, the also radio transmission device of available small-sized light weight replaced the utilization adopted the in the prior art conductance of content and the measuring component parts of liquid level of dielectric constant rate or hyperacoustic reflection.The result, stored the management information of fuel cell system, for example the cycle-index of the characteristic of fuel concentration, content, fuel cassette etc. can realize the sharing as the parts of organize content thing simultaneously, can also obtain the so good effect of small-sized light weight of storage container.In addition, under the situation of the size that can not change storage container integral body, because the component parts that do not need used in the prior art Content Management to use,, can realize the effect of long-timeization of the operation of fuel cell system in addition so can become the space that holds fuel greatly.
Have generator unit portion 221 that direct supply methanol solution 1511 generates electricity in the cell of fuel cell 220, can be connected to storage container 150, and with methanol solution 1511 from storage container 150 after fuel feed pump 222 that above-mentioned generator unit portion 221 supplies with, the power transfer that will be produced by generator unit portion 221 be to be suitable for the voltage of electronic equipment 210, supply to electronic equipment 210 voltage conversion circuit 223, constitute the outside transceiver 180 of above-mentioned sending/receiving system 190.Outside transceiver 180 is delivered to having in the control of microcomputer device 211 that electronic equipment 210 possessed with the balance information of detected methanol solution 1511.
In addition, consider that along with the posture change of storage container 150, liquid level 151a changes, the distance 140 unascertainable situations between RFID label 101 and the outside transceiver 180 storage container 150 being installed under the situation of electronic equipment 210 that can be portable.In order to address this is that, for example can adopt this spline structure shown in Figure 10.Promptly, under the state of the position relation each other of having fixed three groups of radio-type transport unit 101-a that each group is made of IC tag 120 and antenna 12,101-b, 101-c, use the RFID label 1101 that on a base material 11A, has disposed three groups of radio-type transport unit 101-a, 101-b, 101-c.This RFID label 1101 swims on the liquid level 151a of the liquid 151 in storage container 150.Relative therewith, be provided with the antenna 161 of an outside transceiver 180.In addition, among Figure 10, illustrate the antenna 161 of outside relatively transceiver 180, the state that liquid level 151a tilts.By adopting this structure, even in posture change along with storage container 150, under the situation that liquid level 151a changes, also can use three radio-type transport unit 101-a, 101-b, 101-c and antennas 161 apart from d1, d2, d3, decide the distance 140 of antenna 161 and liquid level 151a, and no matter the posture of liquid level 151a.
Fuel surplus management method in the application system 201 that constitutes so as mentioned above is described.
With the instruction of the validation of information relevant with fuel when the control device 211 of electronic equipment 210 sends to the outside transceiver 180 of cell of fuel cell 220, the dispensing device side control part 170 of outside transceiver 180 is in order to read in the data of storage in the RFID label 101 in the storage container 150, for example the performance data of fuel sends the data return instruction with certain power to RFID label 101.Received the control of the RFID label 101 of this electric wave by the control part 126 of RFID label 101, the reception information of voltage 1291 after quantizing with above-mentioned data with by coding circuit 129 turns back to outside transceiver.Thus, outside transceiver 180 obtains representing to be the data and the reception information of voltage 1291 of fuel cell-use fuel from RFID label 101.
The dispensing device side control part 170 of outside transceiver 180 is obtained range information 140 between outside transceiver 180 and the RFID label 101 according to above-mentioned reception information of voltage 1291 as mentioned above.Thus, can hold the surplus of the methanol solution 1511 in the storage container 150.
In the performance data of having confirmed fuel, for example after the inner capacities in the concentration of methanol solution 1511 and the storage container 150, by fuel feed pump 222 sucking-off methanol solution 1511 from storage container 150, and supply to generator unit portion 221, thereby begin generating by generator unit portion 221.After will being converted to the voltage of regulation by voltage conversion circuit 223 by the power of generator unit portion 221 generatings, supply to electronic equipment 210.
After generator operation began, outside transceiver 180 regularly communicated with RFID label 101, and after obtaining receiving the information of information of voltage 1291 from RFID label 101, managed the surplus of the interior methanol solution 1511 of storage container 150 successively.And, be setting when following in the surplus that is judged as methanol solution 1511, outside transceiver 180 is sent this content to the control device 211 of electronic equipment 210.Thus,, carry out demonstration that for example fuel is few etc., supervise fuel exchange and fuel supplement etc. by electronic equipment 210.In addition, the information stores of the liquid level that also periodic measurement can be gone out is at least one of outside transceiver 180 and RFID label 101.In addition, also can and measure the imagination residue driving time that shows fuel cell system the elapsed time from the information of the liquid level stored.
In addition, in the fuel surplus management method in above-mentioned application system 210, RFID label 101 will receive information of voltage 1291 and turn back to outside transceiver, but as described, also can constitute layback information 140.In addition, outside transceiver 180 the antenna 12 of the antenna 161 of the outside transceiver 180 of decision and RFID label 101 apart from the time, also can send by predetermined output voltage, under the situation outside the distance decision, send by other output voltage and RFID label 101.
The following describes the another example of application system with above-mentioned sending/receiving system 109 grades.
The sending/receiving system 190 that Figure 11 represents to have said external transceiver 180 and above-mentioned RFID label 101 be applied to the to infuse structure of management system 301.This transfusion management system 301 is that the example of using sending/receiving system 190 is wrapped in the used transfusion of drop in the medical space of hospital etc.In addition, be example with medical transfusion here, but be not limited to medically, also can be applicable to have from this storage container the transfusion management system of the structure of discharging the liquid in the storage container.
Held transfusion 3101 in the transfusion bag 310, parts 303 built-in or that loaded as the RFID label 101 of radio-type transmitting device swim on the liquid level of transfusion 3101.As an example of parts 303, also can use and adopt the encapsulation (kapsel/capsale) that transfusion is not produced the material of baneful influence, built-in RFID label 101 in this encapsulation.Concrete, can use and the material identical materials that constitutes transfusion bag 310.The management information 1271 that information storage part 127 internal memories in RFID label 101 contain the kind that comprises the information relevant with the transfusion 3101 of this transfusion bag 310, for example medicine, concentration, capacity, use valid expiration date and the information relevant with the transfusion tundish vessel etc. is used as id information.The information that also can further comprise the patient of infusion 3101 as above-mentioned management information 1271.
In this transfusion management system 301, outside transceiver 180 and transfusion control part 312 have been installed in transfusion retainer 311.Transfusion control part 312 be equivalent to the to infuse control section of management of state of transfusion 3101 of bag 310 is connected by wired or wireless and outside transceiver 180, has microcomputer 3121 and communicator 3122.Microcomputer 3121 is carried out the relevant processing of condition managing of wrapping 310 transfusion 3101 with transfusion.Communicator 3122 to transfusion bag 310, outside transceiver 180 and transfusion control part 312 display unit 313 that the is provided with relevant information of management of sending and infuse of being separated by.In addition, also can make outside transceiver 180 and transfusion control part 312 constitute one, in this structure, show and adorn 313 to be attached to transfusion control part 312 or outside transceiver 180.
In this transfusion management system 301, identical with aforesaid execution mode, the transmission receiver side control part 170 that contains in the outside transceiver 180 is obtained the liquid level of transfusion 3101 according to this communication distance of obtaining behind the communication distance of obtaining with RFID label 101.Here, dispensing device side control part 170 is had above-mentioned apart from the above-mentioned dispensing device side storage part 1711 that contains in the determination section 171 in the case of this example, have a plurality of forms corresponding to a plurality of transfusion bags 310, the above-mentioned use corresponding to the form of employed transfusion bag 310 apart from determination section 171 obtained communication distance with RFID label 101.Further, the best information of store patient in dispensing device side storage part 1711, at this moment, dispensing device side control part 170 by with transfusion bag 310 in the communicating by letter of RFID label 101, also carry out patient's contrast.
The action of the transfusion management system 301 that as above constitutes like this is described.
If transfusion bag 310 is set on transfusion retainer 311, then outside transceiver 180 communicates with RFID label 101, and the above-mentioned id information of reading and recording on the information storage part 127 of RFID label 101.Comprise in above-mentioned id information under patient's the situation of information of infusion 3101, dispensing device side control part 170 contrasts with the patient information that is recorded on the dispensing device side control part 170 in advance.Be suitable for to begin drop under this patient's the situation by the consistent transfusion bag 310 that is judged as of result, the patient information of contrast.And, carry out the measurement of the liquid level of transfusion 3101 by the periodic communication of RFID label 101 and outside transceiver 180.And if the above-mentioned liquid level measured by outside transceiver 180 is below the prescribed level, then dispensing device side control part 170 reduces signal with surplus and outputs to transfusion control part 312.
On the other hand, the result who is judged as based on the contrast of the patient information of dispensing device side control part 170 at dispensing device side control part 170 is that transfusion bag 310 is not suitable under this patient's the situation, and dispensing device side control part 170 outputs to transfusion control part 312 with warning signal.In addition, judge under the situation that the valid expiration date of transfusion 3101 ends at dispensing device side control part 170 and too warning signal is outputed to transfusion control part 312.

Second execution mode
In the above description, RFID label 101 adopt pay close attention to receiving sensitivity and have structure shown in Figure 1, be the structure of coding circuit 129.But the structure of RFID label is not limited to this, even for being provided with the structure of the function that detects garble, also can obtain the effect identical with above-mentioned RFID label 101.Following simple declaration garble measuring ability.
That is, generally in the data communication of the mistake when having supposed communication, Reed-Solomon various error correcting codes such as (reed-solomon) are added on the data, and the frequency that is modulated to permission sends.During reception, after demodulation, decoded data, and use above-mentioned error correcting code to correct to have and transmit wrong data division, and become correct data.
The method of code communication data has various, judges 1,0 method when being chosen in decoding in this communication path easily.In 1,0 judgement, even certain threshold level, also can be by 1,0 relatively judge.
For the Code And Decode of the signal level of communication data, under the situation that does not have non-linear component on the communication path, the communication data that complete decoding received, and can the fault processing data.On the other hand, under the situation that has produced noise on the communication path, produce with certain probability distribution,, become result with certain probability false judgment data then by the relativeness of data and noise if regard this noise composition as.
The false judgment data are to send reception by error correcting code is added on the data that should send, and to decoded data, see the relation with this error correcting code, thereby can misjudgment position, i.e. garble position.But, when on decoded data, having produced wrong more than the error correcting capability, but become identification error, but the state that can not correct.
The probability of happening of garble is subjected to about the distribution of noise, if noise profile is assumed to Gaussian Profile, then is the curve shown in Figure 16 A.
Under the situation of RFID label, the distance by communication path square, received signal reduces.Thus, if the noise in the communication path is assumed to necessarily, then S/N compares square having worsened because of distance.If produce mistake in when communication, then as mentioned above, pass through the error correcting code of being added, according to the relation of data, can the particular error position, can detect wrong number, i.e. the number of errors present.Surpass predetermined distance at communication distance, when having produced above wrong of supposition, only, can not carry out the specific of errors present by discerning excessive mistake.On the other hand, shown in Figure 16 B, if communication distance then can accurately be measured communication distance according to above-mentioned wrong number for detecting wrong scope (KL).
In addition, as among Figure 16 B by shown in " distance L ", if communication distance, promptly the distance of RFID label and outside transceiver is too short, then receiving intensity is strong excessively, so do not make a mistake, the possibility of the measurement that can not communicate distance is arranged.
In this second execution mode, as mentioned above, pay close attention to the relation of communication distance and wrong number, the above-mentioned wrong number that comprises in the notion with garble is that communication distance is obtained on the basis.That is, the RFID label can adopt the structure that is provided with the function that detects garble, and Figure 14 represents an example of this structure.
As the RFID label 501 shown in Figure 14 of an example of radio-type transmitting device, replace the coding circuit 129 in the RFID label 101 and have garble testing circuit 510, replace control part 126 and have control part 515.In addition, garble testing circuit 510 is the notions that are contained in receiving circuit 125, and receiving circuit 125 is connected on the control part 515.Other structures are identical with structure in the RFID label 101 shown in Figure 1.

In addition, as mentioned above, in the scope shown in Figure 16 B that the distance of RFID label and outside transceiver is too short " distance L ", can not communicate the measurement of distance in the prior art.In the RFID label 501 in the present embodiment, in order to address this problem, garble testing circuit 510 adopts structure shown in Figure 15.
That is, garble testing circuit 150 has signal strength signal intensity change portion 511 and false judgment portion 512 by the function branch.Signal strength signal intensity change portion 511 is the parts that change the intensity of the reception electric wave that is received by antenna 12, has level and changes circuit 521, selects circuit 522, amplifying circuit 523.Level changes circuit 521 and for example is made of the resistance partitioning circuitry that is provided with a plurality of resistance, is to come the circuit of forcibly changing by the signal strength signal intensity of the reception electric wave of antenna 12 receptions by the combination of selecting a plurality of resistance.Selecting circuit 522 to be connected to level changes on the circuit 521, be the selection signal of sending according to control part 515 5251, selection has the circuit of the reception electric wave of best signal strength signal intensity from a plurality of reception electric waves with each signal strength signal intensity that level change circuit 521 is supplied with.Amplifying circuit 523 is connected to selects circuit 522, is to amplify from the circuit of the electric wave of selecting circuit 522 supplies by the magnification ratio that can measure the ultimate range that should measure.Here, but should to carry out the ultimate range of above-mentioned measurement be the distance that the distance L shown in Figure 16 B and measuring distance KL addition are formed to what is called.
False judgment portion 512 is connected to signal strength signal intensity change portion 511, is to communicate wrong detection from the reception electric wave that has changed intensity, and this testing result is delivered to the part of control part 515, has decoding circuit 524 and error judging circuit 525.Decoding circuit 524 is connected to amplifying circuit 523, is the decoding of carrying out from the reception electric wave of amplifying circuit 523 supplies, and detects the head of decoded data, is converted to the circuit of the reception serial data that can carry out error detection.Error judging circuit 525 is connected to decoding circuit 524, is the circuit that detects wrong number from the above-mentioned reception serial data that decoding circuit 524 is supplied with, and detected wrong number is delivered to control part 515.
Control part 515 is delivered to above-mentioned selection signal 5251 and is selected circuit 522 when not supplying with above-mentioned wrong number from error judging circuit 525, makes above-mentioned selection circuit 522 is selected to have reception electric wave than the intensity a little less than the signal strength signal intensity of output before.
Thus, garble testing circuit 510 is before can detecting above-mentioned wrong number, repeat signal strength signal intensity and change, when detecting garble, will change attenuation rate that the combination of the resistance of circuit 521 determines, promptly select level number and wrong number to deliver to control part 515 by level.In addition, above-mentioned attenuation rate has represented how to reduce to degree the level of signal strength of the reception electric wave that is received by antenna 12, and the ratio that changes the whole resistance in the circuit 521 with the resistance relative level of using is represented.
